British heavyweight champion David Price has revealed he is in no doubt that Audley Harrison will be the toughest test he has faced in his career to date.

Price, an Olympic bronze medallist in 2008, has won all 13 of his professional contests, and many feel he has the tools to become a world champion over the next couple of years.

Before he can turn his attentions to that, he must get past Harrison, who won gold at the Sydney Games in 2000 - but whose reputation was shredded when he was crushed by David Haye, then the WBA champion, inside three rounds in November 2011.

Price is refusing to focus on that bout, and instead is readying himself for an inspired performance from the 40-year-old.

"It's my biggest test so far without a doubt," Price said. "If people want to judge Audley on the David Haye fight that's up to them, but I won't be doing that. I'm judging him at his best and when he's at his best he's dangerous for anyone in the world so it's a good step up for me from someone like Sam Sexton.

"No disrespect to Sam, but he's not in the same league as someone like Audley Harrison. I'm looking forward to testing myself against the best Audley Harrison possible.

"I'm glad he's injury-free, I'm in this game to test myself and to get to the top and I think this fight will be brilliant for me. I'm going to have to answer a few questions, against a different type of style I'm going to have to deal with.

"It's going to do a lot for my development and it whets my appetite. I know Audley Harrison inside out. I was on the England squad at the time when Audley won in Sydney, and I looked up to him."
